FIRE-WORK.

- SPECIFICATION forming part of Letters Patent No. 377,730, datedFebruary 7, 1888.

I Application filed April 18, 1887. Serial 1510235203, (No model.) I

of Jersey City, in the county of Hudson and State of New Jersey, haveinvented a certain new and useful Improvement in Fire-Works, of whichthe following is a specification.

The improvement relates particularly to fire-works used for signaling.

The improvement consists in the combination,with a signal, of ignitingmaterial applied to the end portion thereof which is to be lighted, anda part or appurtenance provided with complementary material which, whenrubbed against the igniting material upon the end of the fire-work, willserve to light the same.

The igniting material upon the end of the fire-work is intended to besimilar to that used upon safety-matches. It will preferably beprotected from dampness or water by the cover, and in such case thecomplementary material may advantageously be applied to the exterior ofthe cover. It cannot ignite when rubbed against any material other thanthe complementary material, nor can it ignite by percussion; hence thefire-work will be perfectly safe to carry. If a cover is used and coatedwith complementary material, as de scribed, the cover will be removedwhenever the fire-work is to be ignited,'and that portion which hasapplied to it the complementary material will be rubbed against saidigniting material, whereupon the fire-work may be easily ignited. Thecomplementary material, when applied to the exterior surface of thecover,will be protected, preferably, by a cap of rubber or likematerial,which may he slipped over it, and this will constitute afeature of my improvement.

In the accompanying drawings, Figure 1 is a side. view of a signalembodying my improvement. Fig. 2 represents a central vertical sectionof a fire-work and cover embodying my improvement. Fig. 3 is an end viewthereof.

Similar letters of reference designate corresponding parts inall thefigures.

A designates the case or shell of the firework. It may be made of a thintube of paper, wood, ormetal. As this fire-work isspecially intended foruse as a signal, the tube A is intendedto contain a composition whichwill produce a slow-burning colored fire.

quick-burning composition, of, which, after the combustion of eachsection of slow-burning composition,- will operate quickly to throw offthe accumulated scoria.

Thesignal at one end is provided, as here shown, with a spike, .a,whereby it may be fastened in an upright position to' any desirablesupportas, for instance,a railroad-tiebehind a train as a signal to anapproaching train.

The upper end of the signal will be coated with an igniting material,I), which preferably will be of the same character as the materialapplied to those friction-matches which can only be ignited by strikingthem upon a specially-prepared surface which is usually applied to thecontaining box. The complementary material I) in the present example ofmy invention is applied to the exterior of the closed end of a cover, B,which is intended to be slipped upon that end of the signal to which thesaid igniting material is applied. The cover will protect the ignitingmaterial from dampness and water. As the complementary material is onthe exterior of the cover, there is no danger of its coming in contactwith the igniting material of the signal. To ignite the signal, thecover will be removed and that end or portion which has thecomplementary ma-' terial applied to it, and will be rubbed across theigniting material, whereupon the signal may be easily ignited. The coverwill be made fore the cap 0 is applied thereto. By pulling the free endof this strip the capv C may be easily and quickly removed.

I do not wish to be restricted to the applica-' tion of the saidcomplementary material to the cover, as I may apply it to some otherpart or appurtenance of the firework.

That I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with aease or shell, of composition for producing anilluminated signal contained therein, and provided at one end' withigniting material capable of ignition only when brought into contactwith a certain complementary igniting material,and a cover having saidcomplementary material applied to its exterior surface, substantially asspecified."

"whose exterior surface has said complementary igniting material appliedto it,"'substantially as specified.

3. The combination, with a case or shell, of

composition for producing an illuminated sig- 25 nal containedtherein,and provided at one end with igniting material capable ofignition only when brought into contact with a certain complementaryigniting material, a cover having said complementary igniting materialapplied 30 to its exterior surface, a cap adapted to'fit over theportion of the cover which has this material applied to it, and a stripof tape or like material,whereby such cap may be easily and quicklyremoved, substantially as speci- 35 fied.
